The research, sponsored by the U.S. Office of Juvenile Justice and Delinquency Prevention, involves a comprehensive literature review, a national mail survey of juvenile corrections and parole officials, telephone interviews with the directors of recommended programs, and onsite factfinding at 23 programs in 6 States. The identification and review of key topics and issues in juvenile intensive aftercare include definitional considerations, target populations, assessment and classification for risk and need, and theory-driven program interventions. The intervention model for juvenile intensive aftercare encompasses the following features: the integration of social control, strain, and social learning theories; 5 underlying principles for programmatic action; 3 program elements and 5 sub-elements; and 10 service areas. This report advises that the provision of more intensive, highly specialized, individualized services should reflect the correctional system's increased ability to assess and identify more precisely the problems and needs of diverse juvenile offenders. 2 figures and 87 references
